title: [Myocardial viability: update in nuclear cardiology].
abstract: Evaluation of myocardial viability with the aid of radionuclides, is a technique that offers reliable, reproducible information, with an attractive cost-benefit relationship, in the study of the myocardial viability, integrating cardiac molecular, metabolic, and functional aspects. Nowadays, coronary risk stratification in post-myocardial infarction patients pretends to locate them as low-, intermediate, and high risk-subjects that can suffer cardiovascular complications in the very near future. Low-risk patients are characterized by a cardiac-related mortality below 1%, whereas high-risk mortality is greater than 3%. Because of clinical complications following a myocardial infarction are observed during the first month of evolution, clinical guidelines suggest to evaluate the cardiovascular risk before hospital discharge.
